1 )FueJ
If the engine runs in summer, the Chinese grade 0 light diesel
fuel (GB252 -81 ) is to be' used, and in winter ,the 10 light diesel
fuel is to be used.
The fuel to be used must be clean and settled for a period of
time (generally not less -than 48 hours.). A furtherfiltering~is nec-

rings and other grades of lubrcating oil to prevent the: bearings,
piston rings and other grades of lubricating oil to prevent the bear-

3)Cooling Water
It is recommended to use soft water such as clean river water,
rain water aIld snow water ,etc. forellgine cooling. The soft water
containing less minerals will or less scales after heating so that the
cooling system will not clogged up easily. If the bard water con~
taining much minerals is often used, the cylinder head' will be Qver-
